Where the measurements are

Heat marks show satellite measurements. Orbit tracks are modelled; glow sizes and place-label positions are display context.

200 km

What each mark means

  • VIIRS (NASA)375 m—

    No detections stored for this frame.

  • Meteosat (EUMETSAT)about 1–3 km per cell—

    Measures radiated power, which is what sizes the glow. Its individual pixel positions are not stored, so no Meteosat footprint is drawn — inferring one from the sharper layer would put a detection pixel on ground nobody measured.

  • True geographic scale, corrected for latitude. Frame is about 884 km across.
  • At this scale both sensor footprints are smaller than a pixel, so no true-scale square is drawn. Two squares clamped to the same legible minimum would show a 1:1 ratio for a 5:1 fact.
  • The glow means “an event, roughly here”. Its area follows the measured power and its radius is capped, because an uncapped one would assert a burnt extent nobody measured. The number carries the magnitude.
  • Grey marks detections shown as history, including those on quiet or archived events. It does not establish that a later satellite pass measured no activity.
  • At country scale each event is one glow. Individual 375 m detections resolve on the event page, where they are larger than a pixel.
